Increased diversity in the workforce can lead to either more or less discrimination. We study discrimination among recruits in the Norwegian Armed Forces during boot camp. In a vignette experiment female candidates are perceived as less suited to be squad leaders than their identical male...

We study how close personal contact with minorities affects in-group and out-group trust in a field experiment in the armed forces. Soldiers are randomly assigned to rooms with or without ethnic minorities. At the end of the recruit period, we measure trust by using a trust game. Results...

To what extent is labour mobility in the European Union a threat to the strength of unions? We argue that the combination of cheap labour, workforce heterogeneity, and low unionization among labour immigrants' is a potential challenge for unions. The challenge will be particularly severe if...

To what extent do early experiences in the host country shape the political integration of immigrants? We argue that the initial neighborhoods immigrants settle in establish patterns of behavior that influence subsequent political participation. Using Norwegian administrative register data, we...

Recent research suggests that using additional teachers to provide small-group instruction or tutoring substantially improves student learning. However, treatment effects on test scores can fade over time, and less is known about the lasting effects of such interventions. We leverage data from a...

Coordination in collective wage setting can constrain potential monopoly gains to unions in non-traded-goods industries. Countries with national wage coordination can thus stabilize overall employment against fluctuations and shocks in the world economy. We test this theory by exploring...

We report results from a large-scale, pre-registered randomized field experiment in 159 Norwegian schools over four years. The intervention includes students aged 7-9 and consists of pulling students from their regular mathematics classes into small, homogenous groups for mathematics instruction...

We study the importance of linguistic diversity in the workplace for workplace productivity. While cultural diversity might improve productivity through new ideas and innovation, linguistic diversity might increase communication costs and thereby reduce productivity. We apply a new measure of...

Have recent trends in globalization changed the positive link between trade openness and social insurance? The consensus view - that voters want better social insurance against income loss the more open the economy - is seemingly contested by the rise of populism and the China shock. We present...
